Nanomachines could revolutionize technology and modern medicine, if only we had viable power sources to make them move where we wanted them to go. Now scientists at the University of Cambridge have built the world’s tiniest engines, powered by light, as described in a new paper in the Proceedings of the National…

One of science fiction’s biggest unfulfilled promises are medical nanobots: tiny little machines that will run around your body, repairing what’s gone wrong. Scientists from the University of Houston are setting out to change all of that, with an incredibly clever self-assembling robotic gun that can clear blockages…

Researchers from the University of California have developed acid-fueled micro-machines capable of traveling and delivering cargo directly inside a living creature. It's a breakthrough that's expected to significantly advance the field of medical nano-robotics.

Whether they're sneaking between cells or turning cockroaches into living 8-bit computers, nanobots are insanely fascinating. Now, they're about to become an army of impossibly small weaponized robots, swarm into the human body, hunt down malignant tumors and destroy them once and for all.

A team of Dutch engineers just published the details of a curious new invention: tiny robotic sperm that can be controlled with a weak magnetic field. Like real sperm, these so-called MagnetoSperm flip their tails to swim towards their target. Unlike real sperm, they're made of metal-coated polymer.

We already have the potential to reconfigure DNA into itty bitty bio-computers programmed to do our bidding. But now, scientists have used high numbers of those nanobots to successfully complete logic operations inside of actual, living organisms. Say hello to the computerized cockroach.

Sometimes it's refreshing to find a song with a very candid title. Enter They Might Be Giant's "You're On Fire," which is not only a kickin' tune, but also literally about people being on fire. There you go.

Will the wonders of carbon nanotubes never cease? Engineers have now used everyone's favorite cylindrical übermolecules to create artificial muscles that can contract and twist, in a manner not unlike like the muscles found in elephant trunks and squid tentacles. The upshot? Researchers say these tiny little motors…

Jeff and Ashley Sierzenga recently took it upon themselves to bring to life the flesh-eating nanobots from Jeff Carlson's bestselling series Plague Year. Here you can see their entire project, from schematics to the final model.

Yesterday we learnt that scientists have created the first nanobot assembly line. It's "manned" by four spider-like nanocreatures made from DNA strands, with three arms and four legs. That's what you are looking at in this image.

Look close. You may be staring at the end of cancer. Those tiny black dots are nanobots delivering a lethal blow to a cancerous cell, effectively killing it. The first trial on humans has been a success, with no side-effects:
